FIELD OF THE INVENTION

The present invention relates to systems and methods for encoding, reading and decoding machine-readable data encoded in three-dimensional rotatably-readable encodings of data configured for optical rotational machine-reading.

BACKGROUND OF THE INVENTION

Current methods of encoding data in a printed encoding typically comprise encoding a string of data in static one- or two-dimensional black and white encodings, such as barcodes and QR codes. The amount of data which can be encoded in such encodings is typically limited by the size of the area available for printing of the encoding and by the size of a reader suitable for machine-reading of the encoding.

The present invention seeks to provide a novel method of encoding data which utilizes both a third dimension of the encoding, as well as a speed of rotation of the encoding while being read, to encode data. The present invention thereby facilitates significantly increasing the amount of data which can be encoded in an encoding printed on a given area over current methods which employ static one- and two-dimensional encodings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Reference is now made to FIGS. 1A and 1B, which are simplified pictorial illustrations of examples of an object bearing three-dimensional rotatably-readable encodings of data configured for optical rotational machine-reading, constructed and operative in accordance with a preferred embodiment of the present invention. The rotatably-readable encoding of data configured for optical rotational machine-reading illustrated in FIG. 1A preferably includes a multiplicity of three-dimensional concentric curves 100 encoding data. Three-dimensional concentric curves 100 are preferably formed on a surface 102. Alternatively, three-dimensional concentric curves 100 may be formed on an article separate from surface 102, such as, for example, a sticker or a label, which is then fastened to surface 102.

Surface 102 may be, for example, a generally circular surface as shown in FIG. 1A, or a surface of any other suitable shape or dimension. Surface 102 typically forms part of a product 104, product 104 preferably being the subject of the data encoded in three-dimensional concentric curves 100. Product 104 may be, for example, a consumer product or a container having an interior volume, which volume contains a solid or liquid product such as, for example, fresh food, preserved food or raw food. The data encoded in three-dimensional concentric curves 100 may include, for example, instructions which, when read by a computer, cause the computer to process product 104 or the contents thereof in accordance with the instructions. Alternatively, the data may include, for example, a price of product 104, a catalog number of product 104 or an expiration date of product 104.

It is a particular feature of this embodiment of the present invention that three-dimensional concentric curves 100 are formed to reflect light impinging thereupon while surface 102 is rotated in a plane coinciding therewith, the characteristics of the reflected light representing the data encoded within three-dimensional concentric curves 100.

The characteristics of the light reflected from each of three-dimensional concentric curves 100 preferably comprise at least one of an angle of reflection of the reflected light and an intensity of the reflected light, however it is appreciated that the reflected light may have additional characteristics associated therewith. It is appreciated that the characteristics of the light reflected from each of three-dimensional concentric curves 100 correspond to physical characteristics of a corresponding one of three-dimensional concentric curves 100. The physical characteristics of each of three-dimensional concentric curves 100 may include, for example, a color of the curve, a length of the curve, a distance between the curve and an adjacent concentric curve, and a height of the curve as dictated by a physical coating of the curve or by the material forming the curve. These characteristics of the curve are fundamental in characterizing the light reflected from the curve, and are therefore suitable for encoding data. It is further appreciated that the speed of rotation of surface 102 while light is impinged onto surface 102 also characterizes the light reflected from each of three-dimensional concentric curves 100. Therefore, three-dimensional concentric curves 100 may encode a multiplicity of data sets, wherein encoded data of each data set is represented by light reflected from surface 102 while surface 102 is rotated at a corresponding speed.

Turning now to FIG. 1B, there is shown a rotatably-readable encoding of data configured for optical rotational machine-reading which includes a multiplicity of three-dimensional non-overlapping straight lines 150 which non-overlapping straight lines 150 encode data. Three-dimensional lines 150 are preferably formed on a surface 152. Alternatively, three-dimensional non-overlapping straight lines 150 may be formed on an article separate from surface 152, such as, for example, a sticker or a label, which is then fastened to surface 152.

Surface 152 may be, for example, a generally circular surface as shown in FIG. 1B, or a surface of any other suitable shape or dimension. Surface 152 typically forms part of a product 154, product 154 preferably being the subject of the data encoded in three-dimensional non-overlapping straight lines 150. Product 154 may be, for example, a consumer product or a container having an interior volume, which volume contains a solid or liquid product such as, for example, fresh food, preserved food or raw food.

The data encoded in lines 150 may include, for example, instructions which, when read by a computer, cause the computer to process product 154 or the contents thereof in accordance with the instructions. Alternatively, the data may include, for example, a price of product 154, a catalog number of product 154 or an expiration date of product 154.

It is a particular feature of this embodiment of the present invention that three-dimensional non-overlapping straight lines 150 are formed to reflect light impinging thereupon while surface 152 is rotated in a plane coinciding therewith, the characteristics of the reflected light representing the data encoded within three-dimensional non-overlapping straight lines 150.

The characteristics of the light reflected from each three-dimensional non-overlapping straight lines 150 preferably comprise at least one of an angle of reflection of the reflected light and an intensity of the reflected light, however it is appreciated that the reflected light may have additional characteristics associated therewith. It is appreciated that the characteristics of the light reflected from each of three-dimensional non-overlapping straight lines 150 correspond to physical characteristics of a corresponding one of three-dimensional non-overlapping straight lines 150. The physical characteristics of each of three-dimensional non-overlapping straight lines 150 may include, for example, a color of the line, a length of the line, a distance between the line and an adjacent line, and a height of the line as dictated by a physical coating of the line or by the material forming the line. These characteristics of the line are fundamental in characterizing the light reflected from the line, and are therefore suitable for encoding data.

It is further appreciated that the speed of rotation of surface 152 while light is impinged onto surface 152 also characterizes the light reflected from each of three-dimensional non-overlapping straight lines 150. Therefore, three-dimensional non-overlapping straight lines 150 may encode a multiplicity of data sets, wherein encoded data of each data set is represented by light reflected from surface 152 while surface 152 is rotated at a corresponding speed.

It is a particular feature of this embodiment of the present invention that three-dimensional concentric curves 206 are formed to reflect light impinging thereupon by light impinging and detection functionality 210 while product 202 is rotated in a plane parallel to surface 204, by rotating functionality 200. The characteristics of the reflected light represent the data encoded within three-dimensional concentric curves 206.

The characteristics of the light reflected from each of three-dimensional concentric curves 206 preferably comprise at least one of an angle of reflection of the reflected light and an intensity of the reflected light, however it is appreciated that the reflected light may have additional characteristics associated therewith. It is appreciated that the characteristics of the light reflected from each of three-dimensional concentric curves 206 correspond to physical characteristics of a corresponding one of three-dimensional concentric curves 206. The physical characteristics of each of three-dimensional concentric curves 206 may include, for example, a length of the curve, a distance between the curve and an adjacent concentric curve, and a height of the curve as dictated by a physical coating of the curve or by the material forming the curve. These characteristics of the curve are fundamental in characterizing the light reflected from the curve, and are therefore suitable for encoding data.

As further described hereinabove with regard to FIG. 1A, it is also appreciated that the speed of rotation of product 202 by surface rotating functionality 200 while light is impinged onto surface 204 also characterizes the light reflected from each of three-dimensional concentric curves 206. Therefore, three-dimensional concentric curves 206 may encode a multiplicity of data sets, wherein encoded data of each data set is represented by light reflected from surface 204 while product 202 is rotated at a corresponding speed.

The system of FIG. 2A also preferably includes data decoding functionality 220 operable, responsive to detecting light reflected from three-dimensional concentric curves 206 by light impinging and detection functionality 210, for decoding the data encoded in three-dimensional concentric curves 206.

Rotating functionality 250 may be, for example, a motorized turntable. On surface 254 there is provided a three-dimensional rotatably-readable encoding of data configured for optical rotational machine-reading such as the three-dimensional rotatably-readable encoding of data illustrated in FIG. 1A, which includes a multiplicity of three-dimensional concentric curves 256. As described hereinabove with regard to FIG. 1A, three-dimensional concentric curves 206 may be formed on surface 204 or may be formed on an article separate from surface 204, such as, for example, a sticker or a label, which is then fastened to surface 204.

It is appreciated that the system of FIG. 2B is also suitable for optical rotational machine-reading of data encoded in other examples of three-dimensional rotatably-readable encodings of data, such as, for example, the three-dimensional rotatably-readable encoding of data illustrated in FIG. 1B.
